4,4'-methylenebis[N-sec-butylaniline]|MDBA|5285-60-9

★ Introduction

Chinese Name: 4,4'-双仲丁氨基三苯基甲烷,mdba,5285-60-9

MDBA Is A Trade Name Of 4,4'-Methylenebis[N-Sec-Butylaniline]|MDBA|5285-60-9, Which Is A Liquid Secondary Diamine, Since The Hydrogen Atom On Each Amino Group Is Replaced By A Sec-Butyl Group , In A Limited Space, The Combination Of Active Hydrogen Atoms And Sec-Butyl Groups Produces Many Unique Properties, The Amino Moiety Forms The Urea Bonds That Affect The Hard Segments, While The Butyl Groups Act As Internal Plasticizers. It Is Connected With The Polymer Matrix, Neither Leaching Nor Precipitation. While The Alkyl Group Increases The Solubility Of The Diamine So That It Can Be Mixed With Almost Any Polyol And Polyamine.


★ Advantages:

Liquid, Safe And Easy To Operate

Kettle Long Life

Low Toxicity - Ames Test Was Negative

Increased Mobility And Adhesion

Low Humidity Sensitivity

Can Be Used For The Maturation Of MDI Prepolymer

Compatible With A Variety Of Polyol Coacervatives And Other Polyurethane Chemical Materials

Can Be Used For Room Temperature Curing

Hard Foam: Enhanced Compressive Strength Dimensional Stability, Reduced Fragility, High Porosity, Low Thermal Conductivity 

TDI Soft Foam: Low Density, High Strength, High Loadability 

MDI Soft Foam: Low Density, Low Hardness, Enhanced Strength


★ Product Use

4, 4'-Methylenebis [N-Sec-Butylaniline]|MDBA|5285-60-9 Can Be Used In Rigid Foam, Soft Foam, Paint, Adhesive, Sealant, Elastomer, The Typical Use Of Polyol 1- 5%. 4,5'-Methylenebis [N-Sec-Butylaniline]|MDBA|5285-60-9 Can Also Be Used To Spray Polyurea, And A Variety Of Metal And Concrete Repair For The Compound.

Soft Foam

Bulk Foam - Adding 3-5php Of 4,4'-Bis-Sec-Butylaminodiphenylmethane-MDBA To Improve The Tensile Strength, Tear Strength And Load Of The Foam In Standard TDI And High Resilience Foam Compositions Performance, In Most Cases, These Advantages In Reducing The Foam Density Can Be Achieved In The Polyester Foam, The Same Proportion Of 4,4'-Methylenebis [N-Sec-Butylaniline]|MDBA|5285-60-9 Can Significantly Improve The Tear Strength And Loadability Without Affecting The Other Properties Of The Foam.

Cold Molded Foam - Has Been Proven In Commercial Applications By Adding 1-2php 4,4'-Methylenebis [N-Sec-Butylaniline]|MDBA|5285-60-9 To Reduce The Density And Soften The Foam So That The Foam Properties Optimization. But Also Can Enhance The Tensile Strength, Tear Strength And Elongation, Shorten The Release Time.


Hard Foam

Polyurethane Rigid - Use 3-5php Of 4,4'-Methylenebis[N-Sec-Butylaniline]|MDBA| 5285-60-9 In A Water or Anhydrous Hard Foam System To Significantly Improve The Compressive Strength And Size Of The Foam Stability, While Reducing The Fragility, Improve The Porosity, Reduce The Thermal Conductivity.

Polyisocyanurate Hard Foam - Add 5php 4,4'-Methylenebis [N-Sec-Butylaniline]| MDBA|5285-60-9 In The System To Increase The Compressive Strength By 100% In A High Proportion Of Water or Full Water Foaming, The Dimensional Stability Is Significantly Improved.


Coating / Adhesive / Sealant / Elastomer

Coatings - 4,4'-Methylenebis [N-Sec-Butylaniline]|MDBA|5285-60-9 Room Temperature Ripening Of Coatings For TDI And MDI. With Suitable Catalyst Co-Curing Agents, It Can Be Used For Spraying, Casting Method Of The Composite Material System. The Formulation Of 4,4'-Di-Sec-Butylaminodiphenylmethane-MDBA Is Used As A Curing Agent To Improve The Adhesion And Surface Quality.

Adhesive-4,4'-Methylenebis [N-Sec-Butylaniline]|MDBA|5285-60-9 Makes The Substrate Better Wetted And The Cured Polymer Is Better Adhered To The Coated Surface. The Hard Elastomer - 4,4'-Bis-Sec-Aminodiphenylmethane-MDBA Can Be Used For The Maturation Of MDI Semi-Prepolymers To Produce A Series Of Elastomers With High Hardness.

The Use Of 4,4'-Methylenebis [N-Sec-Butylaniline]|MDBA|5285-60-9 As A Curing Agent Can Extend The Life Of The Kettle To Produce Soft Elastomers Used As Industrial Sealing Materials.


★ Polyurea

Reducing The Rate Of Gel Reaction, Making It Possible To Produce Such High Hardness Polymers By Spray Casting Techniques. The Extended Gel Speed Can Improve The Adhesion With The Base Layer, The Mobility, The Bonding Between The Coating And The Surface Quality. The Use Of 4,4'-Methylenebis [N-Sec-Butylaniline]|MDBA| 5285-60-9 As A Curing Agent, Can Significantly Improve The Impact Resistance Of Polymer Low Temperature Performance.
